With 2.1.10x programs run as root by root with uid==gid euid==egid
are not dumpable. So you can't core dump programs as root. This
seems to be because
if (current->euid != current->uid || current->egid != current->gid ||
!cap_isclear(current->cap_permitted))
current->dumpable = 0;
doesn't account for the superuser - who has special rights but shouldnt
be stopped from core dumping as those rights are (in normal unix anyway)
not 'raised' but implicit.
